ATTACHMENT FOR INTERNAL-COMBUSTION ENGINES.

' e eiuzen ef the United scenes, residing ee mentar-y front lelevation of t Winsted, in the county 'of McCloud and State of Minnesota, have invented certain new and useful Improvements in Attache ments for Internal-Combustion Engines, of which the following is a. specification.

This invention relates to attachments for automobile motors and has particular reference to the well-known Ford motor, formng part of th'e well-known Ford automo- An object of the invention is to provide extension means whereby the timer mechanism on the Ford motor may be moved from 'its present location to the opposite side of the crank shaft and located in the upper portion of the interior of 'the hood.

A further object of the invention is to provide a device adapted to fit into the recess and toextcnd therefrom upwardly and 'out- Wardly away from the exhaust manifold.

' Other objects will be pointed out us they ap ar in the specification.

inafter described and claimed.

Figure' 1 of the drawing represents a frage Ford motor,

Fig. 2 is a side view of same,

Fig. 3 is a longitudinal sectional view of the invention,

Fig. 4 is a perspective view of the same,

Fig. 5 is a vertical sectional view of the present Ford timer casing fitting into a recess on the engine,

Fig. 6 is n cross section through the gear casing of the invention, showing the movable cover, and

Fig. 7 is a perspective view of the cover alone.

Referring to Fig. 1 of the drawings, A represents a Ford four cylinder lnotor or engine, B is a circular cover fastened by means of bolts C to the housin of the engine forming the outer wall o a chamber surrounding the cam shaft (not shown in drawings) into which lubricating oil for the crank casing is injected by means of the oil inlet E, In the center of the cover B Specification of Letters Patent.

Application filed VJuly 2B, 1918. Serial No. 247,178.

providedrfor` the present Ford timer, (which latter is mounted on the cam shaft) he' invention consists in the construction combination, and arrangementv of parts here- Patented Dee. 23, 1919.

(Fig. 5) is a recess 2 wherein the regular present Ford timer casin F lits.

G is the crank or driving shaft of the motor and H is a stub shaft, the pulleys I and J 'heilig mounted thereon respectively, the two pulle s being engaged by an end-` less belt L w iereby the fan K carried by the shaft H is driven.

Between the belt L and the cover B as indicated in Fig. 2, there is a comparatively narrow space. through which applicants device is projected, the im rtance of which will hereinafter he pointe out.

Referring to Fig. 3 of the drawings, 1 represents the cylindrical wall of the! gear 'casing of npplicants invention and 2 the cover thereof. The cover 2 removably lits as by means of recessed joint 3 over the cas ing 1 (the cover being conical in shape, somewhatsimilar to the regular Ford timer casing (Fig. 5) so as to be held in position at its apex by the spring arms 4 and M secured on the engine y means of the bolts C.

The lower edge of the casing 1 is adapted to 'fit into the recess 2 at resent on Ford engines necessitating no ciange to attach applicants device.

A hub 6 Eaxially tangentially arranged on the peri hcry oi the casing and integral therewit i und holding journaled the timer shaft 7, has counter-bore 8 in its outer end to rotatably hold journalcd the'lower end of the tubular member 9 which is formed at its upper outer end with the'circular transverse plate 10 having a anged edge 10.

he shaft# rotatably incased in the tubular member 9 extends beyond the anged plate 10 thereof and carries securely on said extended part a transverse timer arm 11 carrying a spring pressed carbon contact point 12 at its outer end.

A cup 13 [its with its rim into the recess formed by the lian e on plate 10, said cup being made rof in'su ating material, such as fiber or rubber, and carrying the terminal sts 14 in its outer fece, said posts pro- ]ecting therethrough and forming contact points over which the carbon 12 rides to close tlie'electric circuit to reduce a spark when the shaft 7 is actuated? From the posts 14 the and supported on the tie rod N which leads l.

wires are led to from the radiator O rearwardly to the dashboard of the ca r (not shown) the wines being suitably distributed from this location. Thus the shaft V and` the tubular member ma be terlned extension members.

l orking in the g'ear casing 1 are a pail' of intermeshing helical gears 15 and 16 adapted to transmit motion from one shaft to another, the shafts beingr disposed at right angles to each other, the gear 15 being firmly mounted on the lower end of the timer shaft 7 and the gear 16 firmly mounted on the caln shaft 1).of the engine.

It will be noted that the casing 1 is comparatively narrow when the cover is removed, so that the device maybe insert/ed from the right hand side of the motor leftward (with reference to Fig. 1) between the belt L and the cover B and into the re cess 2 in the latter without removing said belt.

Projecting upwardl and outwardly away from the cam shaft any suitable timer mechanism at the outer end of the extension members 7 and 9 may be firmly held in working position by a lilik 17 rotatably holding the tubular member 9 at a point between its ends and adapted at its u )per end to be bolted in position b v means oi regular bolts I of the water conduit of the en ine y f' hus the tubular member 9 incasing the shaft 7 is rotatably held in an oblique position the shaft 7jbeing driven from one side of tie 'crank shaft and crossing the latter, actuating the arm of the timer on the opposite side thereof. A lever arm .18 aving setscrew adjustment on the tubular casing 9 has pivotal connection with rod 19 at its outer end.

The rod 19 is operatively connected with the control rod on the steering post Q of the motor car whereby when the control rod is operated the. timer element on the end of the tubular member J may be oscillated to change its position relative to that of the. timer arm on the shaft 't'. Thus the. spark may be advanced or retarded as desired.

Referring back to the gears 15 and 16. (Fig. 3) 2O rc iresents on the fiat ends of the teeth of tie Lreais. indicating' marks, each of said gears hearingr such marks on certain teeth whereby their position relative to each other is indicated. i

The gear 16 as hcrcinbefore stated in rigidly mounted on the cam shaft D and in the process of attaching applicants device` it would bo very difficult to cause the marked teeth to mesh as desired, unless provision were made whereby the. genis may be seen through the narrow space between the radiator O and the gear casing 1.

The removable coi-'er 2 is provided for this purpose to make it possible to see the gears from the side of the machine so that the y the marks 20 may bebrought into pro r relationship when attacl'iing the device the engine. This feature isV ver important because if it were not so rovi ed it would be necessary to remove tie entireradator involving the breaking of the water connec- .tion at the top of the engine.

'While I have shown a specific form of timer 4in Fig. 3, I wish it understood that l may use the regular Ford timer in itsstead and that applicant does not claim any improvementsI 1n timer devices.

In.the )resent Ford arrangement of the timer to tlie left of the fan mechanism and immediately adjacent the oil intake funnel E, the wires leading from the timer are constantly spattered with 'oil and grease.` The wires and the make and break mecha- 'nism at the outer end of the tubular mem-V ber 9 are also subject to the intense heat radiated from the feed manifold S which injures the insulation on the wires and said mechanism. i

Thus with the construction plirants device may be attached to the motor without requiring any special provision vfor attachment such as drilling` holes or" roiiiit ingiibblts.

i'. paiioif outwardly extending spring' clips 22 on the plate 10 are adapted to removably holda timer element such'as tho cup 13, n notch 21 in the flange adapted to receive a pin on the element to insure its correct rep acement when 1t has been removed.

I claim:
